(cosmetic) Error message is badly worded
0000087: There is no line number when a phrase's implicit return cannot find a default value
The decision phrase in the source has an implicit return for when the repeat happens zero times. That return corresponds to no text, but in a large project it would help authors to at least point to the offending phrase. Also, in this case it wouldn't hurt to give some more explanation of <no text>.

Problem. I am unable to put any value into the return value '<no text>', which needs to be a meditation, because there is no meditation in the world.
 See the manual: 4.12 > Values that vary
The balcony is a room.
A meditation is a kind.
To decide what meditation is the ex nihilo meditation:
repeat with the idea running through the meditations:
decide on the idea.
No tags attached.

Fixed. Inform now produces a much more helpful problem message here, and links to the declaration of the phrase, since that's where the unkeepable promise is made.
